Therefore, it is important that fast algorithms are devised for minimum distance. We propose a scalable variant of a known algorithm for exhaustive search of the minimum distance. The proposed algorithm is based on smart thread management in order to speed up the exhaustive search. The algorithm is particularly efficient when applied in combination with genetic algorithms for code design as a part of code evaluation and can be easily deployed on grid or cloud computing systems.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116411161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their ad-hoc nature, the expected great density of deployment and their closed registration policy may result in multi-layered networks with base stations' ranges constantly overlapping and non-registered users struggling from the accumulative interference. In this paper, we propose a mechanism where femtocells operate in clusters, and may decide to turn to sleep mode if capacity demand of its users is met adequately by the remaining awake femtocells. We propose a special version of hybrid access targeting only users of neighboring femtocells, in order to reduce the number of active base stations and thus, to reduce interference. We enforce sleep mode under conditions that ensure the increased throughput of each involved registered user and the increased capacity provided by the entire cluster with the extra benefit of reduced energy.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114153493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal is to achieve compromise between good resolution and reduced cross terms. The quantitative measures used for this optimization are described. For the case of a simulated signal a measure based on mean squared error is proposed. The proposed method compares an optimized result to the ideal representation obtained as sum of Wigner-Ville distributions of mono-component signals. Three simulated signals are used to compare optimization of Choi-Williams Distribution, Gabor spectrogram, Short-time Fourier transform and S-method. The optimization is realized on the basis of four quantitative measures: Rényi entropy, Jones-Parks measure, Stanković measure and proposed method. Results show problematic use of Jones-Parks measure for optimization and comparable optimization of all tested time-frequency distributions by means of three usable measures. For practical use with real signal, S-method with Rényi or Stanković measure is recommended.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"127 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129850323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An explicit construction of regenerating codes that perform reliability, availability and security of the stored data, and at the same time perform efficient node repair is already provided. Understanding and achieving the optimal tradeoff among the above listed features is of great importance for improving the functioning in all cloud storage systems. Therefore in this work, we propose a new code construction that includes an outer and an inner code in the process. The outer code, Gabidulin code, as a pre-coding step achieves improved security level in the storage system and the inner one, Twin-code framework, performs efficient distribution, reconstruction and repair process. The proposed code is resilient to an eavesdropper model and gives better results regarding the achievements when are used the minimum bandwidth regenerating (MBR) and minimum storage regenerating (MSR) codes, respectively.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125136860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We make the assumption that central users in the network, the so-called “top”, or “power” users, set the agenda, while other, “regular” users often retweet and/or mention their tweets, and behavior towards “top” users differs from the behaviour of “regular” users towards each other. We show that network clustering on Twitter can be observed more distinctively on unimodal projections of specially created bimodal networks (bipartite graphs), where top users in the networks are artificially separated into a second part according to node centrality measures. We evaluate our approach on Twitter-based datasets of mentions and retweets related to Russian political protests and a benchmark English-language Twitter dataset with distinctly polarized clusters; we compare various centrality measures and show that our algorithm yields high modularity in the resulting community structure.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126199159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We introduce an advanced Decode-and-Forward (DF) protocol, referred to as Dynamic Selective Decode and Forward (D-SDF), where each relay individually decides the end of its listening phase and the beginning of its cooperation phase based on a predefined selection strategy. We analyse the outage behavior of this protocol under the assumption that each relay sender employs joint network channel coding and each receiver implements joint network channel decoding, and demonstrate that D-SDF outperforms static SDF in a variety of transmission scenarios.","PeriodicalId":174688,"journal":{"name":"2016 8th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128041261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, we are looking at IEC 61499-based software specifications. Monitoring is done remotely, i.e., the interface behavior of function blocks is streamed to a cloud-based service. Specifications are realized using formal languages such as 1) regular expressions, 2) timed automata, 3) temporal logic. Monitors can be automatically generated from these languages. Using our specifications, we are able to detect abnormal behavior in control software such as timing changes that can, e.g., show the presence of memory leaks or a virus.
